T0 @ZZ whom t may concern.-

Be it known that I, HENRI J. J. CHARLiER, a citizen of the Republic ofFrance, residing in the city and county of Philadelphia, in the State ofPennsylvania, have invented a certain new and useful Improvement inFurnaces, of which the following is a true and exact description,reference being had to the accompanying drawing, which forms a partthereof. l

My invention relates to the construction 'and manipulation of furnacesespecially intended and adapted for melting metals, the object of myinvention being to provide a furnace of great simplicity ofconstruction, one which can be rotated so as to bring different parts ofits walls under the iniiuence of the heating-gases and which may bereadily moved in other ways and other directions.

To these ends my invention consists, generally speaking7 in constructingmy furnace of cylindrical shape and with openings in its ends for theentrance of heating-gases and exit of products of combustion and insupporting and providing for the rotation of the furnace by suspendingit on flexible loops passing over its ends by overhead pulleys orsimilar devices. Preferably the upper ends of the flexible loops aresupported on opposite ends of a central pivotally-supported beam,whereby the furnace can be made to tilt in either direction, andpreferably, also, I support the pulleys for the flexible loops from anoverhead crane, so as to provide for the shifting of the furnace inhorizontal or other directions in accordance with the usual capacitiesof cranes.

Reference being now had to the drawing in which my invention isillustrated, A is the cylindrical furnace, lined with fire-brick, asshown at A', and having at the ends openings A2 and A3 for the entranceof fuel-gas and the exit of products of combustion.

A4 indicates a tap-hole through which the melted metal can be drawn offinto a receptacle H or other convenient receptacle.

B B indicate chain-wheels surrounding the ends of the cylinder. f.

C C are exible loops, preferably chains, as shown, which pass around thechain-wheels B and also around pulleys, as indicated at C C', saidpulleys being journaled in supports C2, which, as shown, are supportedin turn on the notched ends D2 D2 of the beam D, centrally andpivot-ally supported at D on a chain E, the upper end of which issecured to a trolley E by an adjustingenut e', said trolley running on atrack E2, supported on the arm E3 of a crane E3 E4.

F indicates a device whereby combustible material, gaseous or otherwise,can be thrown into the end A2 of the cylindrical furnace. As shown, itconsists of a cylinder F', having a movable bottom F2, supported on anadjusting-screw F2, and a perforated top F, above which is the chamberF5, having an airblast pipe F leading into one end of an exitnozzle F7,lying opposite to the blast-pipe. In practice the cylinder F is chargedwith coal-dust, which is forced up through the perforated bottom E4 bymeans of the movable bottom F2, the coal-dust being caught up by the airentering through the blast-pipe F6 and blown through the nozzle F7 intothe furnace.

G is a stack, and, as shown, a recess g is formed in the stack, in whichis placed the horizontally-movable chamber G', having a lateral port G2,which can be made to register with the stack, and an end port or openingG2, which can be made to register with exitopening A3 of the furnace.This device G is supported by wheels G4 on a track, (indicated at G5.)

In practice the furnace A is gradually heated up-as, for instance, byfirst burning wood in it and then forcing a gradually-increasing amountof mixed air and coal-dust into it until it is at a white heat. It isthen charged with metal, most conveniently through its open end A2, andthis end is then brought into registry with the movable due device G'and further fuel blown in to keep the furnace at the necessary heat.From time to time during the heating of the metal the furnace ispartially revolved by means of the flexible chain C, so as to bringheated portions of the walls beneath the metal and subject the portionsof the wall which have served as the hearth to the heating action of theflames. When the metal is melted, it is tapped off through the tap-holeA4; but prior thereto 'Lit :can be, if desired, moved to any IOOposition Within the range-of the crane. It will be obvious that, ifdesired, the furnace can be discharged through either of its ends A2 orA3 by tilting the beam D and *that the furnace is capable of assumingalmost any desired position, owing tothe character of .its describedconnections.

Having now described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is-

1. A cylindrical furnace, as A, having openings, as YA2 A3, at its endsfor the entrance of fuel and exit of products of combustion `inf portedon said pulleys and passing under and supporting the ends of thefurnace.

3. A cylindrical furnace, as A, having openings A2 and A3 in its endsfor the entrance of fuel and exit of products of combustion incombination with a .crane and means including exible loops C C wherebythe furnace is suspended from the crane and rotated by lmeans of saidflexible loops passing around the ends of the furnace.

Ll. A cylindrical furnace, as A, having openings A? and A3 in its endsfor the entrance of fuel and exit o f products of combustion incombination with a crane, a beam D pivotvally suspended at its centerfrom said crane,

pulleys as C C' supported on the ends of 'said beam and flexible loops CC, passing around said pulleys and around the ends of the furnace saidchains supporting the furnace and serving to rotate it at Will.
